Cemetery notes and/or description:Cemetery notes and/or description:In 1846, nine acres were purchased on Lemp Avenue to serve as the church's first cemetery. As the city of St. Louis grew, it soon became apparent that this small property would not prove to be adequate. In July 1855, the church purchased 34 acres of land at the cemetery's present location on Lucas and Hunt Road from John F. Darby. The first burial at the new location was made in October of that year.

By 1867, the cemetery was again in need of additional land. Nine acres were purchased from John Stevens. In 1897, another 48 acres were purchased from the estate of Jesse Lindell. The final purchases were made in 1911, when an additional 18 acres were purchased from Joseph Gummersbach and 10 acres were purchased from Henry Raterman. These land purchases enlarged the cemetery to its current 119-acre size at the Lucas and Hunt site.

In 1988, St. Peter's Cemetery assumed responsibility for the operation and maintenance of the 28-acre Bethany Cemetery. Located on St. Charles Rock Road, a short distance from the main site, this area is now known as the Bethany Section.
